Unconventional Quantum Criticality in Long-Range Spin-1 Chains: Insights from Entanglement Entropy and Bipartite Fluctuations
Justin Tim-Lok Chau, Jiarui Zhao, Nicolas Laflorencie +1
We study the ground-state phase diagram of a spin-1 Heisenberg chain with staggered long-range (LR) interactions decaying as using a quantum Monte Carlo approach…
Quantum Fisher Information as a Thermal Probe in Frustrated Magnets through Insights from Quantum Spin Ice
Chengkang Zhou, Zhengbang Zhou, Félix Desrochers +3
Quantum Fisher information (QFI) is a measure of multipartite entanglement accessible via inelastic neutron scattering. Here we demonstrate that QFI reveals thermal and dynamical p…
Quantum Fisher Information as a Probe of Critical Scaling in Frustrated Magnets: Signatures from Kagome Quantum Spin Liquid
Zhengbang Zhou, Chengkang Zhou, Menghan Song +2
Quantum Fisher information (QFI) is a measure of multipartite quantum entanglement that can be obtained from inelastic neutron scattering data on quantum magnets. In this work, we…
Thermodynamics of Shastry-Sutherland Model under Magnetic Field
Menghan Song, Chengkang Zhou, Cheng Huang +1
Motivated by the recent experimental discovery of the -linear specific heat in pressurized and magnetized Shastry-Sutherland Mott insulator SrCu(BO), we perform the…
Entanglement architecture of beyond-Landau quantum criticality
Menghan Song, Ting-Tung Wang, Liuke Lyu +2
Quantum critical points beyond the Landau paradigm exhibit fractionalized excitations and emergent gauge fields. Here, we use entanglement microscopy--full tomography of the reduce…
Scaling of Disorder Operator and Entanglement Entropy at Easy-Plane Deconfined Quantum Criticalities
Jiarui Zhao, Zi Yang Meng, Yan-Cheng Wang +1
We systematically investigate the scaling behaviors of the disorder operator and the entanglement entropy (EE) of the easy-plane JQ (EPJQ) model at its transitions between the anti…
